ALX Protocol Python Reference Implementation
The Python implementation provides ALX core protocol behavior for Python, AI, and data workflows.
It is a peer reference implementation. It does not define protocol truth. Protocol truth is defined by protocol/spec.md, protocol/schemas/, test-vectors/, and protocol/error-codes.json.

| Ed25519 signing | Supported |
| P-256 signing | Supported |
| EIP-712 signing | Not bundled |
EIP-712 is an optional Ethereum-compatible signing suite. It is not required for core protocol conformance.
Install for Development
cd reference-implementations/python
python -m venv .venv
.venv\Scripts\activate
pip install -e ".[dev]"
On macOS or Linux:
source .venv/bin/activate
Run Tests
pytest tests/
Protocol conformance adapter
The Python conformance adapter is:
reference-implementations/python/conformance_adapter.py
From the repository root:
node conformance/bin/run.js --impl "python reference-implementations/python/conformance_adapter.py"
Canonical Graph verification
validate_graph(seed, source, context) verifies the reachable Block Graph and returns one of valid, invalid, incomplete, or resource_limit_reached. The result is scoped to the supplied verification context and exactly follows the canonical Graph verification envelope.
The older two-argument validate_graph(graph, context) adjacency form remains available for compatibility. New integrations should use the canonical three-argument operation.
